I have the Eismeer Blue and I would say it's very close to the Steel Blue that you can see if you google blueBaby blue and then take the link to Wikipedia. In the example shown, Steel Blue is toward the end of the color hues.
I only saw the Thunder Blue on the dealers lot and both the salesman and I thought it was Black until we saw the window sticker. It was a grey day. I personally do not like Black cars and so didn't give the car another thought.
When I went to the dealer, I had already made my mind up on Eismeer Blue as I saw one at the Auto Show a few weeks earlier.
I also have the cornsilk interior and think it's great.
That's my story and I'm sticking with it.
